Devolution in the United Kingdom

In the United Kingdom, devolution (historically called home rule) is the Parliament of the United Kingdom's statutory granting of a greater level of self-government to parts of the United Kingdom, such as to Scotland, Wales, Northern Ireland and parts of England, specifically to strategic authorities. Statutory powers have been awarded to the Scottish Parliament, the Senedd (Welsh Parliament), and the Northern Ireland Assembly, with authority exercised by their associated executive bodies: the Scottish Government, Welsh Government, and Northern Ireland Executive respectively.
